Need help with NM Throne Room/Summit Solo (Duo also possible)

[DrayGon777]

Been trying to get the NM campaigns knocked out and mostly been doing this solo, however these two maps seem to give me the biggest problem. Apprentice Towers don't seem to cut it, and while squire towers last longer, I still find my crystal getting taken out before I can finish the boss.

Stats:
Tower Countess: 790/960/203/297 (main focus of gear upgrading atm)
Tower Apprentice: 154/998/366/549
Aura Monk: 559/658/383/595
Trap Huntress: 386/621/363/490

Main Apprentice DPS: 595/688/283/291 (also has 184 Tower Health) 600k+ Normal DPS
Resists 78/66/66/66

Most of my characters still have gear that can be upgraded, so if I need to upgrade more before attempting I will gladly do so. Hoping to get these knocked out before the next Eternia mob shows up not knowing how that will affect gameplay.

Also have 9 other level 74 characters (one Squire Wall) that might also be able to be used but will require a lot more upgrade time/gear searching. :(

Has some layouts for it. I did mine with similar states, except my tower app has 843 Tower Health.

i used bowling balls for every staircase and bouncers in the middle to kill spiders, leaving me with enough DU once boss came (no more wyvern so sell harps, you can even sell walls and **** because no ogres either) to have approximately 3 harps at each spawn. i had 6-8 of them set up already prior so they had a few upgrades, and i added the other one in later. you run around with CTA and an app or hunt guardian repairing the harps shooting the boss, dodging his fire breath and you should be able to win eventually with those stats. I would just keep the builder out because you're not relying on DPS which is severely reduced in NM, you want that builder bonus so your base can hold its own NP, and just let the harps work their magic on the boss. probably will take more than half an hour

throne room: this is a case of pointing more harpoons left than east, bouncering most of the spider spawns and ideally trip starring the east bouncers so you don't have to worry about them as much when dealing with the boss. run circles around the boss when he reaches your harpoon range and with repairing and app/hunt guardian he should eventually go down. you may have to repair north and east a few times but obviously only do this when west just got repaired

With the apprentice builds, I probably will need a dedicated repairer (likely myself) so I'll see if I can get someone else to distract the boss. For the other build, I'll give that a shot. Kinda got into using a lot of ballistas and didn't think to use cannonballs. Tend more towards Apprentice anyways as is evidenced by my main DPS.
